Losartan belongs to the class of medicines called angiotensin II receptor antagonists. Losartan works by blocking the action of some natural substances that tighten the blood vessels.


What is Losartan?


Losartan is a medicine that is prescribed by doctors for patients who require treatment for heart failure and high blood pressure. Moreover, it is said to protect against other health conditions such as diabetes and kidney disease. Not only does this treat many health issues but it also prevents any future heart attacks, strokes, or kidney problems. People with enlarged hearts and high blood pressure can also benefit from Losartan as this medication is said to lower their risk of strokes. 


As part of the group of medications called angiotensin II receptor blockers or ARBs, Losartan is similar to other medicines and drugs such as Cozaar, Diovan, Avapro, and Atacand. Accordingly, Losartan entices the same effects as ACE inhibitors, which are referred to as another drug that targets blood pressure. However, it doesn’t function the same way. While ACE inhibitors aim to relax the veins and arteries, ARBs block out the source of the problem. In this case, it’s the angiotensin II which is a type of chemical that works by narrowing blood vessels within the body. 


This is a prescription-only medication, which means that you can only be cleared to buy this from pharmacies and supermarkets if your doctor has determined that you need Losartan. This medication comes in tablets, displaying different types of colors according to your dosage and brand name. As such, the available dosages and strengths are as follows: 25 mg, 50 mg, 100 mg. 


How does Losartan work?


Drugs and medicines work by blocking out certain effects that the body’s natural substances and reactions bring. When it comes to Losartan, the main target is called angiotensin II, which is the natural substance in the body that tightens the blood vessel. In blocking out the effects of angiotensin II, Losartan helps relaxes and widens the blood vessels and arteries that are found in your heart. As a result, it becomes easier for blood to flow through these vessels. Therefore, the risk of developing any type of heart disease is lessened considerably because of low blood pressure. 


What should you know before taking Losartan? 


Not everybody is suitable to take Losartan, even though it is highly recommended by doctors as a second-choice treatment for people who need another medicine that doesn’t give them a dry, irritating cough. Accordingly, Losartan is suited for young adults who are aged 18 years old and above. Children who are aged 6 years and above can also take this medicine but it’s only to treat high blood pressure. 


Here is a list of things you need to inform your doctor during your consultation: 


  • If you’ve had an allergic reaction to Losartan or other similar medications. 
  • If you have diabetes 
  • If you’ve had heart, kidney, or liver problems
  • If you’ve recently received a kidney transplant
  • If you’ve suffered from diarrhea or vomiting 
  • If you’ve been on a low salt diet 
  • If you have low blood pressure 
  • If you’re currently trying to get pregnant, are already pregnant, or if you’re breastfeeding an infant child 


This way, your doctor can determine the best course of action and medication for your health condition. 


What are the benefits of taking Losartan? 


Lowered blood pressure can lead to many health benefits, especially for older people who are more at risk of developing dangerous heart conditions. If your blood pressure is constantly high, then this will negatively affect the walls of your arteries and blood vessels. Over time, they will wear out to the point that it can cause you to have stores, heart attacks and kidney problems.


What are the side-effects of taking Losartan? 


Like all drugs and medicines, Losartan may cause your body to react in certain ways. This isn’t necessarily a cause for alarm but it’s important to know what is considered common or uncommon for some people. Not everybody will experience all of these side-effects but these are the ones that have been commonly observed and reported on. Below, you’ll find a few examples of what these common side-effects are: 


  • Dizziness 
  • Vertigo 
  • Headaches
  • Nausea 
  • Vomiting
  • Diarrhea 
  • Joint pain
  • Muscle pain 


Most of these side-effects will fade in time. But if they persist and disrupt your daily routine, then you should consult a doctor. Your doctor might prescribe you a different but effective medicine to fix your blood pressure. 


Other people have also been observed to experience uncommon side-effects, which are more serious and should be immediately reported to your doctor. Once you experience the following side-effects, give your doctor a call and consult them about changing your medication. Here is the list of the uncommon side-effects when taking Losartan: 


  • Yellowish skin
  • The whites of your eyes turn yellow 
  • Severe stomach pains
  • Pale skin 
  • Exhaustion
  • Purple spots
  • Bleeding
  • Sore throat and fever
  • Irregular heartbeat
  • Pins and needles 
  • Muscle cramps
  • Weakness 


How do you take Losartan? 


Losartan should be taken once a day with a glass of water. You can take it even if you haven’t eaten a full meal. Accordingly, it is suggested that the first dosage should be taken before bedtime because the effects can cause you to be dizzy. In taking the first dosage, you should be able to rest immediately. Once the first dose is done, then you can take Losartan at any point in the day. To stick with your schedule, you should drink Losartan at the same time every single day to ensure that you won’t forget to take it properly. 


Depending on your treatment or your health condition, your doctor will prescribe a different dosage for you. Usually, adults have been recommended to take a 50 or 100 mg tablet every single day. The starting dosage is 50 mg but for some patients, this can be increased to 100 mg. This is to ensure that their high blood pressure is treated and that their kidneys are protected well. 


However, the dosage is lowered for people who have recently lost body fluids, which can be caused by a number of reasons. This includes having diarrhea, being sick, or being over the age of 75. For kids who are below 17, the doctor usually uses their weight as a way to measure the right dosage for them. 


It usually takes about 3 to 6 weeks for the maximum effects of Losartan to fully set in. 


Where can you purchase Losartan? 


Losartan can be purchased at any local pharmacy. However, because it’s a prescription-only medication, you need to have a prescription given by a doctor. This way, you can easily buy your medicines without any hassle. For online purchasing, you still need to provide a prescription. If you don’t have one, then you can set an appointment with an online doctor as many virtual pharmacies offer this alternative.
